+HISTORY:
+2013/06/26 - v0.1 - first working version to be bundled with chemmacros
+2013/07/06 - v0.1a - fixed stupid bug in `upgreek' mapping
+ - added error messages and added \renewchemgreekmapping and
+ \declarechemgreekmapping
+2013/08/24 - v0.2 - new mappings `mathdesign', `fourier'
+ - new functions: \chemgreek_int_to_greek:n and
+ \chemgreek_int_to_Greek:n
+2013/11/20 - v0.2a - fixed typos in `fourier' mapping
+ - added missing \prop_clear: to \__chemgreek_set_mapping:nn
+ - added missing argument to message calls
+2014/01/24 - v0.3 - rename \Chem<name => \chem<name>, the old names will
+ issue warnings but still work
+ - new mappings `textalpha' (cf the package with the same
+ name, part of `greek-fontenc')
+ - \chemgreek_new_mapping:nnn redefined so that package name
+ must be given if needed; \chemgreek_activate_mapping:n
+ now issues a warning if the needed package hasn't been
+ loaded
+ - if hyperref has been loaded with package option `unicode'
+ and `textalpha' package has been loaded, too, we can use
+ greek letters in PDF bookmarks
+ - new command \printchemgreekmapping
+ - \showchemgreekmapping now writes information to the log
+2014/01/29 - v0.4 - add mapping `fontspec'
+ - new command \printchemgreekalphabet
+2014/08/07 - v0.5 - split from `chemmacros' bundle as independent package
+
